PARAFFINE-PAPER MACHINE.

SPECIFICATION forming part of Letters Patent No. 367,886, dated August9, 1887.

Application filed July 31, 1886. Serial No. 209,642.

Be it known that I, DAVID A. ANDREWS, of

Boston, county of Suffolk, and State of Massachusetts, have invented anImprovementin Paraffine-Paper Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts. v

This invention has for its object to provide apparatus in which paper orother material may have applied to its surface paraffine or otherwan-like substance. The paper or other materialis laid,preferablyinsheet form,upon an endless: belt or apron caused to travel beneath andin contact with a roller or cylinder, which applies the paraffine orother wax-like substance upon the paper or other material laid upon thesaid endless belt or apron. The cylinder or roller referred to hassecured to it and forming the surface thereof a layer of 'felt or otherlike material,which has the paraffine or other wax-like substanceapplied orimparted to it by a second roller, the latter roller alsohaving a layer of felt or other material secured to it, which receivesthe paraffine or other wax-like substance from a suitable receptacle,shown as placed above it. The rollers or cylinders referred to will beinclosed. in a chamber heated sufficiently to maintain the par-affine'or other wax-like substance in a sufficiently softened or fluid stateto permit it to be taken from the receptacle and evenly applied to thepaper or other material by the cylinder or rollerin contact therewith.

My invention consists, essentially, of a traveling belt upon which paperor other material is laid, combined with a cylinder or roller locatedabove the belt and adapted tojapply paraffine or other wax-likesubstance to the said paper or other material, and with gearing torevolve the said belt and rotate the said cylinder.

My invention also consists of a traveling belt upon which paper or othermaterial is laid, a cylinder or roller located above the said belt andadapted to apply paraffine or other wax-like substance to the said paperor other material on the said belt, a second cylinder to distribute theparaffine or other wax-like substance upon the first cylinder, and arecepta cle to contain the wax-like material, combined (No model.)

with means to heat the wax-like material in the said receptacle and onthe cylinders, and with gearing to move the belt and rotate the saidcylinders.

Other features of my invention will be pointed out in the claims at theend of this specification.

Figure 1 is a side elevation of an apparatus by which to practice myinvention; Fig. 2, an end view of Fig. 1, looking toward the left; Fig.3, a top or plan view of Fig. 1, with the heated chamber and itscontained pipes removed; and' Figs. f and 5, details to be referred to.V The sides A of a supporting-f rame of anysuitable construction havesecured to their opposite'ends bearings a a, for shafts ca the saidshafts having mounted thereon rollers 'or cylinders a a respectively,over which is passed an endless supporting and feeding belt or ablematerial. The sides A also support bearings b for a shaft, b, hereinshown as located near the center of the apparatus, the said shaft havingat one end a gear-,1), in mesh with a gear, b*, on a shaft, bfllocated,as herein shown, above and in line with the shaft 1). The shaft b hasits hearings in suitable boxes, I), supported in uprights or standardsI), secured to the sides A, and has mounted upon it aroller or cylinder,b (See dotted lines, Figs. 1 and 2.) The standards b above the rollersupport journal-boxes c for a shaft, 0, having a roller or cylinder, othe surface of the cylinders b and 0 having a layer of felt or otherlike material secured thereto.

The shaft 1) is rotated by means of drivingbelt, (not shown, but whichis passed about a pulley, 0 on the said shaft at one side of theapparatus, as shown in Fig. 3,) the rotation of the shaft 1) revolvingthe shaft b through the gears 1) b The revolution of the shaft 11rotates the cyl inder of by means of a belt, 0', passed about a pulley,0 on the shaft 12 (see dotted lines, Fig. 3) and a pulley, c, on theshaft (F, the rotation of the cylinder a causing the endless belt a totravel over it and the'roller a.

As the endless belt is moved, as described, it passes over a smallroller, having its bearings, as herein shown, in slots in the sides Ilot;

A, as elearlyshown in Fig. 1, the said endless beltpassing between theroller d and the roller or cylinder 1), located above it.

The rollers or cylinders b and c' are inclosed within a chamber, if,provided at its top with a receptacle, d", herein shown as conical inshape, (see Fig. 1,) and provided with a narrow neck, (1, through whichthe pal-affine or other wax-like substance passes to the cylinder thesaid parafline being fed into the receptacle through a door, (1 at itstop, provided with a val ve, d, of anysuitable construe tion.

The receptacle d is heated to a temperature sufficient to maintain theparafiiue or other wax-like substance, preferably in a somewhat fluidcondition, by means of a pipe, f, located within the receptacle, thesaid pipe being preferably formed to leave an opening, f, (see Fig. 4-,)through which opening the paraffine or other material passes to the neck11" of the receptacle.

The pipef may have one end connected to a steam-boiler or other sourceof heat and its other endconneeted toacoil of pipe, f located within thechamber (1", the said pipesf maintaining. the pal-affine or otherwax-like substance in a substantially fluid condition on the cylinders.

In operation the paper or other material, preferably in sheet form, islaid upon the endless supporting and feeding belt at one side of thechamber d it being in the present instance supposed to be laid on thebelt at the right of the said chamber in Fig. 1, the endless beltmovingin the direction of the arrow 3, the chamber d being a sufficientdistance above the endless belt a to permit the said belt to passbeneath it. As the endless belt and the paper or other material thereonare passed between the cylinder If and roller (1 the paraffiue or otherwax like substance on the felt or other surface or covering of thecylinder 1) is applied to the said paper or other material as it passesbeneath the said cylinder. The felt or other surface on the cylinder 1)has the substantially fluid parafline imparted to it by the cylinder 0likewise covered with a surface of felt or similar material, thecylinder 0* being rotated, as herein shown, by contact with the cylinder1)". The felt or other surface of the cylinder 0 in its rotation wipesacross the neck (1" of the receptacle (1, receiving therefrom thesubstantially fluid paraffine or other wax-like substance and impartingit to the surface of the cylinder 1), which in turn applies the saidparatline to the surface of the paper or other material carried by theendless belt.

The flow of the substantially fluid paraffine from the receptacle d maybe accelerated by opening the valve d to admit air to the receptacle, orit may be stopped by closing the said valve. The paper or othermaterial, after being covered with paraffine or other waiolikesubstance, will be carried forward by the end less belt toward the endof the apparatus that is, to the left of Fig. 1-and will then be takenfrom the endless belt in any suitable manner, such as by a machine.

In order to remove the paper from the roller I), if it should adherethereto, I have herein shown in Fig. 5 a doctor, consisting of a knifeor blade, h, which bearsagainst the said roller, it being but a slightdistanceabove the belt a, the said doctor detaching the paper from theroller and permitting it to fall upon the belt.

I claim-- 1.
